\ PNEUMATIC SOLE.

SPECIFICATION forming part of Letters Patent No. 508,034, dated November 7, 1893.

Applicationfiled March 2, 1893. Serial No. 464,464. (No model.) i

To all whom it may concern.-

Be it known that I, FILLMORE MOORE, a citizen of the United States, and a resident of Farmington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Boots and Shoes, of which the following is a specification.

My invention relates tofimprovements in boots and shoes having pneumatic soles on.

the inside of the shoe,whereby jars and shocks are reduced and it consists in a peculiar construction of the pneumatic sole, and its arrangement in the shoe, whereby access to the inflating valve is rendered more easy and also the valve and otherparts are protected from injury.

In the drawings hereof: Figure 1, illustrates a longitudinal section of a shoe having my invention in position. In this instance, the toe part and the heel part aremade separate from each other. Fig. 2, illustrates a plan of the invention as shown in- Fig. 1, a portion of the upper leather being cut away. Fig. 3, ill ustrates an elevation sectioned on the line 00,00, of Fig. 1. Fig. 4, illustrates adetail of the inflating valve.

Referring first to the pneumatic sole or cushion for the toe, A, is the upper. B, is the outer sole. C, is the heel. D, is the insole. E, is a rubber bag made air tight and provided at one end with a stem, F, which encircles a steel tube, G, which is turned at right angles and on the other end thereof, is arranged an' inflation valve, H, which may be the same, or substantially the same as that used for inflati g foot-balls. In Fig. 4, I illustrate these parts in detail.

B, is the outer sole, which is cut away at the instep portion in the form of a channel as at I, (see Fig. 2.) and in this channel, the stem G, of the valve and likewise the projecting stem F, of the bag are laid. The valve comprises a barrel part, J, and a screw plug, K. The plug screws down upon apacking L, in the bottom of the channel, I. The packing, of course, has a hole through it for the passage of the air and in theside of the screw plug, K, is a little opening M. The insole D, covers the upper flange N, of the valve and a hole 0, is made through the insole through which the tube for inflating the bag is inserted. When the screw plug K, is turned so as to be lifted above the packing L, air can be blown into and out from the bag E, which may pass into the space below the screw plug K, and through the opening or hole M, in the screw plug, and thence inwardly or outwardly as the case may be after the manner of an ordinary foot-ball valve.

Thecushioning for the heel is in. all respects the same as that for the toe, excepting that it is of a different shape.

Referring now to Figs. 2 and 3, P, is the cushion in the heel. 'R, is the rubber stem projecting from the cushion. S, is the stem of the valve. The valve itself is marked H, the same as at the toe cushion.

In Fig. 3, I show a desirable plan on which the shoe may be made. The upper leather A, is stitched to the boxing T, which goes around the edges of the pneumatic cushions and is stitched to the Welt U. The welt is in turn stitched to the outsole B. The insole D, may be attached with cement in the usual manner.

I claim A shoe having an elastic air tight bag, between the insole and the outsole, a stem on the bag, an inflating tube and valve accessible for the purpose of inflation,the inflating valve and stem being located in a channel made in the upper side of 'the outsole at or near the instep of the shoe, substantially as set forth.

Signed at Palermo, Sicily, this 13th day of February, A. D. 1893.
